"I have got one thing to say to people who do bring cannabis and other drugs or paraphernalia into these Aboriginal communities - we do patrol the highways, we will stop your vehicle, we will search your vehicle and if needed we will put you before the courts," he said.

Senior Sergeant Ripp says the incident should serve as a warning to unwanted visitors.

"I served four notices that they were to leave the community ASAP and never to return to that community," he said.

"If people think they can go into these communities to live, they're wrong. They have to attend at the office and it's only daily visits."
